.LIQUID-SUPPLYING APPARATUS.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application led December 30, 1919. Serial No. 348,454.

To all whom t may concern.'

Be it known that I, MORRIS PARNEs, a citizen of Austria, and a resident of New York city, in the county-of New York and State of New York, have invented certain new and useful Improvements in Liquid- Supplying Apparatus, of which the following is a specification.

This invention has as one of its objects to provide a liquid fuel feed for internal combustion engines, in which an auxiliary tank is automatically supplied with fuel from the main tank by a partial vacuum, which latter tank may be remote, or on a lower plane.

Another object is to create suoli vacuum in the auxiliary tank by communicating means between the. tank and intake manifold of the engine.

A further object is to provide means for automatically controlling the vacuum relative to the level of the fuel in the dispensing tank.

A still further object is to provide an operative device for this' purpose comprised of few and simple parts not easily liable to become deranged.

These objects are attained by the novel construction, combination and arrangement of parts hereinafter described, and s hown in the accompanying drawings, forminga material part of this specification, and in which Figure 1 is a vertical sectional view of a feed apparatus made in accordance with the invention, parts being broken away to show the construction.

Fig. 2 is an enlarged longitudinal sectional view taken through the center of the valve operating means.

Referring to the drawings 1n detail, the numeral -lOvdesignates a supply tank which may be remotely located and below the feed tank 11 with which it is connected. by the pipe 12 entering the head 14 at a point near one side.

A circular plate 15 forms the bottom of the tank 11 and also the top of the dispensing tank 16, the same h aving a t1 ht .lower head 17, these tanks having flange ad]acent ends-clamped by bolts 18 with the plate 15 intermediate.

A pipe 2O leads to the manifold of the engine (not shown) from-the center of the upper head 14 and fixed in the lower end of while in the base of the valve is fixed a tube 26 its bore 27 communicating with the tank chamber through an opening 28 formed transversely in the base of the valve 25.

vThe lower reduced portion 29 of the tube passes through a hollow plug or bushing 30 screw threaded into the plate 15, over which 1s a gasket 31 contained in an inverted cap 32 through which the tube element 29 passes.

A pin 33 passes transversely through the tube element 29, below the bushing 3() and pressing against the extending ends of the pin is another inverted cup 34 acting as a. seat f or the upper end of a coiled compression spring 35 exerting pressure upon a disk valve 36 freely fitting the vend of the tube and held in place thereon by the nut 37, the tube belng open at its lower end, and by the passage 28, permits the passage of air between the feed and dispensing tanks in an obvious manner.

y Fixed in the plate 15 at one side of the center is a hollow-fitting 38, its arm 39 being upturned at the center of the tank 16 and formed into a valve seat 40 to receive the valve 36.

Surrounding the tube 26 is another tube 42, the same forming the central wall of an annular chamber 43 the walls 44 of which are hermetically closed, forming a float, which when in a raised position contacts with the base of the valve 25, and when in a lowered position rests upon a collar 45 fixed on the tube 26, thereby closing the valve 36.

In order to prime the dispensing tank 16, an elbow iittin 48 is secured to one side, the same receiving'a pipe 49 having a horizontally bent portion 50 its o en end having rotatably mounted upon it unnel 51, normally inverted, as shown in full lines, but capable of being reversed, as indicated .in broken lines, and clamped by the bolt 52, in position to receive liquid, which obviously is conducted to the tank 16.

Set in the lower head 17 is atwo-way valve 55 having a part 56 extending into the tank to prevent sediment from entering the passage 57 and which might otherwise passy handle 61 to permlt passage therethrough.

Other openings 62 and 63 allow the sediment to be removed through the valve by action of the handle in an obvious manner.

In operation, the main supply tank 10 having been connected with the receiving tank 11 and the pipe 20 with themanifol of the internal combustion engine with which the device is used, when the'en'gine is in operation a suction' is created producing-a partial vacuum in the tank 11, causing a flow of liquid fuel therein and if contiiued, eventually raises the float 43 and by it closes ythe valve 25 cutting off lthe vacuum and ceasing the suction effect on the pipe 12.

A hollow fitting 38 communicating between the tank 11 and 16 maintains the latter partially filled, thevalve 36being closed only when the float is in a lowermost position, at which time the -effects of the vacuum are taking place, recharging the tank 11.

Due to the springs 24 and 35 an easy and smooth action of the valves are secured, no noise or pounding taking place and it will be clear that if the connections are maintained,

'the filling of the dispensing tank is automatically accomplished at recurrent periods as may be required.

It will also be seen that provision has been made for manually charging or primin the tank 16 when required.

' aving thus described my invention and set forth the manner of its construction, application and use, what I claim as new and desire to secure by Letters Patent, is z-f 1. In an apparatusfof the class described, the combination with a fuel supply source and .-a vacuum producing means, of a tank having an upper and lowerchamber, a tubular connection between said supply source and said upper chamber, a U-shaped tubular connection between said chambers, a connection between said vacuum producing means and said upper chamber,valves controlling the passages in said last named connections, a hollow rod engaging between said valves, said hollow rod being open to both chambers above the liquid therein, and a float operable in said upper .chamber whereby said valve rod is raised or lowered according to the iuctuation of said float.
